Description

Technical Field

[0001] The invention relates to the technical field of rail unloading, and in particular to a self-powered rail unloading vehicle with an adjustable rail dropping curve. Background Art

[0002] Existing T11BK long rail transport trains typically consist of a generator car, a first safety car, a multi-section rail transport car, a second safety car, a lead car, a first middle car, and a tail car. These tail cars typically have only two conveyors, limited to transporting rails. These conveyors are unable to meet the requirements for the curved transition between rails and landing. This can easily cause the rails to transition abruptly from a straight line to a pre-set curve, potentially generating additional internal stress and even damaging the rails or fasteners. This necessitates manual intervention or auxiliary equipment to guide and position the rails, increasing operational complexity, safety risks, and labor costs, while reducing automation and overall construction speed.

[0003] Furthermore, the power cables need to be transmitted from the first, second, and last railcars through multiple railcars for operation. This requires numerous power connectors, and the contact resistance between the power connectors during power transmission can easily cause voltage drops. During the soft start of the conveyor motor, the soft starter input voltage often drops below AC350V, causing the hydraulic pump to fail to start. Frequent hydraulic pump starts draw high starting currents, burning the power connectors and degrading the power cable insulation. Power connector failures are difficult to troubleshoot on-site, increasing the workload and impacting construction operations. Summary of the Invention

[0004] The present invention aims to solve the technical problems existing in the prior art.

The support roller is located between the two rail unloading guide wheels. A roller groove is provided on the rail guide platform corresponding to the support roller. The support roller is rotatably mounted in the roller groove, with the top of the support roller located outside the roller groove. This satisfies the requirement of supporting the bottom of the rail and reducing friction during rail transportation.

[0010] In the above scheme: a pedestal is provided on the front side of the rail conveyor, the bottom of the front half of the pedestal is inclined forward, and the height of the rear half of the pedestal is flush with the rail conveyor and the rail unloading guide groove; ribs for limiting the rails are provided on the left and right sides of the pedestal at intervals, and the ribs and the pedestal form a limiting groove for the rails to slide, and the pedestal limiting groove is provided corresponding to the rail entrance of the rail conveyor;

[0030] The present invention will be further described below by way of examples and in conjunction with the accompanying drawings:

[0031] like Figures 1 to 9As shown, a self-powered rail unloading vehicle with an adjustable rail drop curve includes a rail unloading vehicle body, which is arranged in the last section of a long rail transport train. The rail unloading vehicle body is provided with a base 1, a rail conveyor 2, a rail unloading guide trough 11 and a rail drop guide platform 8 in sequence from front to back. The bottom of the front half of the base 1 is a slanted bottom arranged forward, and the height of the rear half of the base 1 is flush with the rail conveyor 2 and the rail unloading guide trough 11. The base 1 is provided with side ribs 1a for limiting the rails at intervals on the left and right. The side ribs 1a and the base 1 form a limiting groove for the rails to slide, and the limiting groove of the base 1 is arranged corresponding to the rail entrance of the rail conveyor 2. The rear end of the limiting groove is closed, which can convey the rails to the rail conveyor 2. The rail unloading guide 11 is located directly behind the rail outlet of the rail conveyor 2. A plurality of roller components 3 for pressing on the rails are arranged at intervals in the rail unloading guide 11. A rail pressing component 14 for adjusting the rail drop curve is arranged at the end of the rail unloading guide 11.

[0032] The rail-dropping guide platform 8 is hinged to the rear end of the rail unloading vehicle body. The rail unloading vehicle body is equipped with an adjustment mechanism for adjusting the pitch angle of the rail-dropping guide platform 8. The adjustment mechanism includes a discharge winch 7. The rail unloading vehicle body is equipped with a hoisting column 7d located at the rear side of the discharge winch 7. The top of the hoisting column 7d is rotatably provided with a hoisting roller 7a. A fixing ring 7e is fixed to the rear side of the hoisting column 7d. The middle part of the rail-dropping guide platform 8 is provided with a discharge roller 7c for fixing the wire rope 7b of the discharge winch 7. The wire rope 7b of the discharge winch 7 passes through the hoisting roller 7a and the discharge roller 7c in sequence before being fixed to the fixing ring 7e.

[0033] A pair of hinged support rods 8a are fixedly connected to the front side of the rail-dropping guide platform 8, and two hinged mounting seats are correspondingly provided at the rear end of the rail unloading vehicle body. The hinged support rods 8a are installed on the hinged mounting seats through rotating shafts extending forward and backward to realize the installation of the rail-dropping guide platform 8.

[0034] A pair of rail unloading guide wheels 8b are vertically mounted near the rear end of the rail unloading guide platform 8 to control the left and right position of the rail. The pair of rail unloading guide wheels 8b are spaced apart on the left and right sides, and the rail passes between the two rail unloading guide wheels 8b, and the left and right position of the rail is controlled by the pair of rail unloading guide wheels 8b spaced apart on the left and right sides. A guide plate 8d is vertically mounted on the front side of each rail unloading guide wheel 8b. The front ends of the two guide plates 8d are spaced apart from each other, forming an open shape, which facilitates the rail to pass between the two rail unloading guide wheels 8b.

[0035] The rail guide platform 8, located behind the two rail unloading guide wheels 8b, is equipped with support rollers 8c for padding the bottom of the rail. The support rollers 8c are located between the two rail unloading guide wheels 8b. The rail guide platform 8 has roller grooves corresponding to the support rollers 8c. The support rollers 8c are rotatably mounted in the roller grooves, with the tops of the support rollers 8c located outside the grooves. This provides support for the bottom of the rail and reduces friction during rail transportation.

[0036] The support roller 8c is arranged near the rear end of the rail-dropping guide platform 8, and the rail-dropping guide wheel 8b is arranged close to the support roller 8c.

[0037] The rail clamping assembly 14 includes a rail clamping wheel 14a disposed above the rail unloading guide 11 and height adjustment mechanisms disposed on the left and right sides of the rail unloading guide 11. The height adjustment mechanism is used to adjust the height of the rail clamping wheel 14a. The width of the rail clamping wheel 14a must be smaller than the width of the notch of the rail unloading guide 11 to meet the requirements of the rail clamping wheel 14a moving up and down, thereby pressing on the rail and preventing the rail from being ejected.

[0038] The height adjustment mechanism includes a hydraulic cylinder 13 and a roller guide frame 14b. The bottom end of the hydraulic cylinder 13 is fixed to the rail unloading vehicle body. The roller guide frame 14b is arranged between the rail unloading guide groove 11 and the hydraulic cylinder 13. A strip hole is vertically provided on the top of the roller guide frame 14b for the rotation axis of the rail pressing roller 14a to pass through. The two ends of the rotation axis of the rail pressing roller 14a pass through the strip holes 14c on both sides of the roller guide frame 14b and are fixedly connected to the protruding end of the hydraulic cylinder 13. At the same time, the strip holes 14c limit the movement range of the rotation axis of the rail pressing roller 14a. In this embodiment, the strip holes 14c are notches with an upward opening.

[0039] like Figure 6 As shown, the roller assembly 3 includes an anti-slip roller 3a located above the unloading rail guide groove 11 and an L-shaped bracket 3b located on both sides of the unloading rail guide groove 11. The vertical part of the L-shaped bracket 3b is fixed on the outer side of the unloading rail guide groove 11, and the horizontal part of the L-shaped bracket 3b is located at the bottom of the vertical part and extends horizontally toward the outer side of the unloading rail guide groove 11. An adjustment notch 3f is vertically provided at the top of the vertical part. The rotating shafts at both ends of the anti-slip roller 3a pass through the adjusting notch 3f, and the anti-slip roller 3a is equipped with a pair of supporting screws 3c. The top of the supporting screw 3c is provided with a through hole for fixing the rotating shaft of the anti-slip roller 3a. The horizontal part of the L-shaped bracket 3b is vertically provided with a mounting ring 3e for the bottom end of the supporting screw 3c to pass through. The bottom end of the supporting screw 3c is provided with two nuts 3d, and the two nuts 3d are respectively located on the upper and lower sides of the horizontal part to realize the installation of the support screw 3c.

[0040] The length of the support screw 3c above the transverse portion can be adjusted via two nuts 3d, thereby adjusting the height of the anti-slip roller 3a to accommodate rails of varying specifications. This adjustment is typically completed before transport and does not require further adjustment during transport. The hydraulic cylinder 13 flexibly adjusts the height of the rail-holding roller 14a, enabling real-time adjustment of the rail drop curve. This is a well-designed arrangement.

[0041] There are two groups of rail unloading guide grooves 11, which are spaced apart on the rail unloading vehicle body. There are also two corresponding rail conveyors 2. Two groups of rail unloading guide wheels 8b are correspondingly provided on the rail drop guide platform 8 to improve the rail unloading efficiency.

[0042] The rail unloading vehicle body is also provided with a tool box 5 and a power generation system for power supply.

[0043] The power generation system, including a generator set 6 and an electrical control cabinet 4, supplies power to the unloading winch 7 and rail conveyor 2. This eliminates the need for wiring and power supply from the locomotive, reducing wiring and installation workload. The number of power connectors is significantly reduced, with only two remaining to power adjacent work vehicles. This effectively avoids voltage drops caused by excessive power connectors and prevents power connectors from burning out due to frequent electrical activation, thus simplifying on-site maintenance and ensuring construction efficiency.

[0044] The generator set 6, tool box 5 and electrical control cabinet 4 are installed above the rail conveyor 2 or the rail unloading guide trough 11 through a raised frame, saving space.

[0045] like Figure 8 As shown, a roof 10 is provided on the top of the rail unloading vehicle body, and side walls 12 are provided on both sides of the rail unloading vehicle body. The side walls 12 and the roof 10 cover the components installed on the rail unloading vehicle body, thereby protecting the power generation system from the sun and rain as much as possible and extending the service life. A fuel tank 9 is provided at the bottom of the rail unloading vehicle body.

[0046] like Figure 9 As shown, the rail conveyor 2 is equipped with a conveying winch, which is equipped with a winch motor 209. The rail conveyor 2 is equipped with two conveying motors. The rail conveyor 2 includes bottom support wheels 228 spaced apart in front and back. Conveying pressure wheels 229 are arranged directly above the bottom support wheels 228. The rails pass between the bottom support wheels 228 and the conveying pressure wheels 229. The two conveying motors are used to drive the two conveying pressure wheels 229 respectively. Each conveying pressure wheel 229 is equipped with a pair of rail-pressing cylinders 227. The rail-pressing cylinders 227 press the conveying pressure wheels 229 against the rails, thereby increasing the friction between the conveying pressure wheels 229 and the rails for conveying.

[0047] When in use, first start the generator set 6, and provide power to the vehicle after the output voltage stabilizes. The electrical control cabinet 4 provides power to the rail conveyor 2, the rail pulling winch, the hydraulic cylinder 13 of the rail pressing assembly, and the tail unloading winch 7. The fuel tank 9 under the vehicle is used to provide energy for the generator set 6.

[0048] Then start the conveying winch to pull the rail to the base 1, and then pull the rail to the rail conveyor 2 through the guidance of the sidewall 1a of the base 1.

[0049] The rail conveyor 2 is started to compact the rails and transport them along the rail unloading guide groove 11 to the rail drop guide platform 8 at the tail end.

[0050] Start the unloading winch 7 and adjust the pitch angle of the rail drop guide platform 8 to adjust the rail landing curve.

[0051] When the tail of the rail reaches the vicinity of the rail pressing assembly 14 of the rail unloading guide groove 11, the hydraulic cylinder 13 is started, and the rail pressing wheel 14a is moved up and down by the hydraulic cylinder 13 to limit the upward tilt of the rail, and at the same time, the rail dropping guide platform 8 is lowered to allow the rail to slowly fall to the ground.
